Abstract

There is disclosed a method and an apparatus for measuring of fluid flow in a fluid distribution system, including a centrally located fluid source (LS) which is connected via separate feeding conduits (FC1, FC2, etc.) to a number of fluid tap units (LT1, LT2, etc.), each including at least one fluid tap. The method comprises the steps of providing, for each said separate feeding conduit (FC1, FC2, etc.), a first fluid pressure sensor (PS1, PS2, etc.) located anywhere along said separate feeding conduit or in the associated fluid tap unit (LT1, LT2, etc), and a second fluid pressure sensor (PS'), serving as a reference pressure sensor common to all of said feeding conduits and being located adjacent to said centrally located fluid source (LS). Each of the first and second fluid pressure sensors (PS1, PS2, etc and PS') are connected to a control unit (CU) adapted to determine the fluid pressures at the first and second fluid pressure sensors, including the difference between these two fluid pressures, and, on the basis of said determination of said fluid pressures and said pressure difference, calculate the flow of fluid through each separate feeding conduit (FC1, FC2, etc.), at least as long as there is a fluid flow at said inlet (IN1, IN2, etc) to any fluid tap unit (LT1, LT2, etc.). By carrying out such measurements over a period of time, it is possible to calculate and record the amount of fluid consumed during such a period of time and/or the thermal energy consumed in each fluid tap unit (LT1, LT2, etc.). The fluid tap unit may e.g. be a separate apartment in a building.

Abstract

A method and a fluid tap device for retaining the temperature of a liquid, in particular hot water, in a liquid distribution system having at least one liquid conduit extending from a liquid source to a liquid tap. After completion of a tapping operation and replacing the liquid with gas in the liquid conduit, the refilling of liquid in the liquid conduit is performed in three steps: - a first step, initiated by said liquid tap being activated, the activation of the liquid tap causing a change of a physical variable which propagates backwards along said liquid conduit and initiates a second step, - said second step involving refilling the liquid conduit with liquid from said liquid source, while permitting remaining gas to escape via a gas passage being separate from a liquid passage in said liquid tap, and - a third step, initiated when the liquid reaches said liquid tap, involving opening of said liquid passage and permitting the liquid to flow out via said liquid passage and through said liquid tap.
